Spatial

Total Phosphorus

Total Phosphorus concentrations across the lake for the last two months from grab samples only. If monitoring locations had more than one sample during the period (i.e. structures) average values were calculated.

Lake Okeechobee Loading

Cumulative Flow and Load

Monthly cumulative discharge volume, total phosphorus (TP) and total nitrogen (TN) load (top, middle and bottom, respectively) for lake inflow (left) and outflow (right) for the last three water years.

Flow-Weighted Mean Concentrations

Monthly and 12-month moving average total phosphorus (TP) flow-weighted mean (FWM) concentration (Top) and total nitrogen (TN) FWM concentration (bottom) for lake inflow (left) and outflow (right) for the last three water years.

Monthly and 12-month moving average total phosphorus (TP) flow-weighted mean (FWM) concentration (Top) and total nitrogen (TN) FWM concentration (bottom) for lake inflow (left) and outflow (right) for the last three water years.

Regional Outflow

Monthly cumulative discharge volume, total phosphorus (TP) and total nitrogen (TN) load (top, middle and bottom, respectively) for the Caloosahatchee (S-77; left), EAA (middle) and St Lucie (S-308; right) for the last three water years. Current load calculations only uses grab samples at monitoring locations to estimate nutrient concentrations.
